Hello, i have a problem with over clocking my E2180. I am running it on a P35C-DS3R and cooling it with an Arctic Freezer 7.

It boots at stock, on stock voltage to give me 2.0ghz. I gained some new ram this morning from Ocuk (geil 6400 ull 2gig). My old ram was Corsair Value Select :P 4gig 4300. I can get this baby to 3ghz (thanks to Will Hub :P) at 8 X 380 at 1.45V. 33oc (i) / 65oc(l). Which in my opinion seems a bit high as other people get 3ghz at stock voltage! Ive also spoken to Ikettles about this problem giving me various things to test out. I found out that my computer will not boot at 7X300 (2.1ghz) at 1.45v :/.

Using my old ram i could achieve 2.6ghz with 10 X 265 with my Timings tight Cas4. Using this new ram i have to use cas5 when attempting to hit 3ghz. I have read the guide about upping the MCH and FSB up by +0.1V or .01V what ever it is. My ram ratio is set at 1.1.

Any ideas how i can get to at least 3ghz if not beyond on a lower voltage than 1.4V?


Thanks,
Paul.
 
Yeah I'm having the same problems as you mate! Mine is a brand new 2180 and I can't get mine over 3gig no matter what I've tried. It required 1.42v just to get it stable at 3gig with looping Prime95 tests.

A bit annoying considering others results, but I only bought mine as a stop gap until the new generation of quad cores come out, so I'm not too distraught.

Out of interest I'm using 10x300fsb to reach 3gig and I see you are using 8x380 (or should be 375) for 3gig. Is it actually any faster running the extra FSB?
 
Tbh, i dont see any difference, except that your ram may run slower/faster than it would normally, as the FSB to Memory ratio is different. So no, not that i can tell anyway!
 
I've got an E2180 and DS3R too, but I'm using a Thermaltake Ultra 120.



I currently have GMCH at +0.1v (I'm not sure whether this is really needed though) and my memory at +0.3v (they are rated at 2.1v). I've only tested it for an hour with Orthos and it was stable, I'm not finished with it yet mind.

Have you updated to the latest BIOS? Also check the northbridge is getting hot; I hear some northbridges have rubbish paste and don't transfer heat properly so it may be failing due to that.
 
High FSb usually equates to more memory bandwidth.

I think you need to define stock volts. Lots of people talk about stock as if it was fixed, but anything that is left on AUTO on a modern BIOS will usually adjust itself. Stock could be as low as 1.1V or as high as 1.35V on a 2180. It depends on the motherboard how it handles being asked to overclock on [AUTO] CPU voltage.

The cheaper Gigabyte P35 motherboards suffered from horrible Vdroop which the latest BIOS fixes with the Loadline Calibration option. If you are not running the latest BIOS, I would strongly suggest you get it as it's pretty darn good.

I have an E2180 running stable at 3.6GHz using the following settings on a P35-DS4 (basically the same BIOS layout)





Most folks get hung up on the Northbridge and Southbridge voltages, but make sure you've locked the PCIe bus at something reasonable (100 is the default) and disable as much of the Intel speedstep jiggerypokery as possible.

The other thing that always amazes me is that users will set their RAM timings during CPU overclocking whereas I find just letting the RAM do it's own thing works far better until I've maxed out the CPU.

My Normal V-core is 1.35V i believe.

Hi, and a Happy New Year to you.

I think that's the Max figure printed on the box, isn't it? What is the last number on the MIT screen (as above?)

a. Checked for Vdroop on your board?
b. Checked what the PCIe bus is set to?
c. Downloaded the latest BIOS?

Some pictures of all your BIOS screens as they are currently would be very useful.

I'm not sure about the vdroop but his vdrop is only 0.02v.

Try googling Vdroop vs. Vdrop. I think the spelling is immaterial though as we both know what we're talking about.

0.02 seems very good though. How did he estimate the 0.02 and was that under full load at 1.45V (as set in the BIOS)?
 
Third Law of Overclocking: just because someone else can do it, doesn't mean that you can. I've just started playing with an E2180 on a spare rig and I can only get 3GHz stable at 1.375 set on an IP35. Cooling is a Thermalright Ultra120A (not the Extreme). To get 3.2 stable needs 1.4625, which means the end is near - 3.3 is probably impossible with air cooling. But that's this CPU - I'm sure others can go better, and other still not a well.

Sorry that was a typo, his vdrop was 0.02 :p
 
I will upload some pics A.S.A.P, im just having technical difficulties on getting my pc "working"

Is 65oC underload alright for a 3ghz Overclock? at 1.45V

Sounds good, although what your you measuring temps with.
Had a shock last night when the new CoreTemp was released and apparently my temps are 15c higher than I thought.
 
Well, it's a miracle it boots at all with the PCIe bus massively overclocked like that - set PCIe Express Frequency to something like 100 or 101 to lock it as currently when you increase the FSB, you increase the PCIe bus too.

And maybe give the G(MCH) an extra 0.15 or something. Not much though.
 
Here's some screenshots of my 3.2Ghz OC.
I have more or less the same board as you so you may find them helpful, you may not.
Also noticed form your bios shots that you seem so be running a fairly old bios, try updating to the latest one, helped my OC quite a bit.

I don't think he's paying much attention - about 10 posts back I asked him to update his BIOS and fix the PCIe clock at 100MHz, but the photos still suggest he's not done any of that. His CPU does appear to have a really high VID though - mine is 1.225V, and yours is 1.275V while his is 1.325V. I'm amazed that such a recently released CPU can have such a range of base operating voltages.
 
Ok, ive now finally got my processor to over clock. I'm at 3.0ghz on 8 X 375fsb at about 1.4V and around 60oC Under load. Is it fine running at 60oC? Ive stressed it for 3hours now (3:17pm) and i will continue to stress it.
